My husband & I received a knock at the door very late one night. The woman next door was very drunk & hysterical & had lost her keys, she was very upset so my husband & I helped her by taking her in. I gave her a cardigan to wear as she was frozen & made her a cup of tea before we drove her to her boyfriends house to collect keys. I went over & above that evening to ensure she was ok, at that time we didnt really know this woman but went over & above, phoning around the pubs she’d Been in to find out if her bag/keys had been handed in. Since then she has been overly friendly/interested towards my husband & I told him I don’t like it. Fast forward to a year later. My husband bumped into her on a night out, he was not drinking however she again was in a complete state & my husband (being a good citizen) & his friend offered to give her a lift home. On arrival at her house she asked him to sleep with her. My husband took almost a year to tell me this as he didn’t want any drama. However I feel completely stupid having been friendly with her since. I am so angry now & feel like such a fool. WWYD? Do I pretend it never happened or completely blank her & let her figure it out?
